Cédric Pasteur 7a10ba028a Fixed disjoint clock computation 2012-06-20 17:09:17 +02:00
Cédric Pasteur 8815a2cd03 Better handling of clocks in memalloc
- We can do a better allocation if we take into
account 'when' in extvalues 
(test/good/memalloc_clocks.ept shows the
improvement)
- Fixed a bug with memalloc on records: if we 
translate:
o = { a with .f = u }
to
o = a; o.f = u
then we cannot share u and o.f

Cédric Pasteur ed2c08315b Should be affinity, not copy 2012-06-19 09:33:27 +02:00
Gwenal Delaval 2bd31db883 Causality and scheduling with contracts
Correction of the causality analysis and scheduling (with interference)
to take contracts into account.

Adrien Guatto 8153bc4eb5 Fixed Tomato: did not reconstruct internal clocks of extvalues 2012-03-30 14:47:47 +02:00
Cédric Pasteur 6e2e2a9f47 Fixed bug in interference computation
To know the variables read by an equation, we should
only look at the clock of variables. Otherwise, 
there could be a problem for node calls that 
define new clocks.

Cédric Pasteur 7866321089 Fixed bug in interference 2012-02-09 11:06:28 +01:00
Adrien Guatto 3aeb499cc2 Re-enable interference for enums 2012-02-08 11:13:02 +01:00
Adrien Guatto 1cb4b1154b Memory allocation: do not share enums (and thus clocks). 2012-01-30 17:48:47 +01:00
Cédric Pasteur 2f993a602c Fixed base clock in code generation
Put the base clock inside the equation where it 
belongs.

Cédric Pasteur 06e997e0c8 Fix for -mall
Do not share memories and outputs if they are not
arrays, as it might make the register allocation
by the C compiler less efficient.

Cédric Pasteur b1bd6dbd57 Compare clock repr
Not sure this is necessary but it doesn't hurt to 
check twice.
2012-01-23 16:03:01 +01:00
Cédric Pasteur 2b59ec754a Fix for memories with no uses
Add a fake use to make sure they interfere with
other memories and outputs

Adrien Guatto cad8a0149f Option to perform type inference on all types 2012-01-23 13:36:24 +01:00
Léonard Gérard b49c37f7bf Add ways to declare unsafe functions + unsafe fix 2011-11-21 03:26:26 +01:00
Cédric Pasteur 04b8853a1d Added a new reinit operator
It has type:
reinit: t at r * t -> t at r

It can be used to put a constant value in a 
location.

Cédric Pasteur 0f403e3694 Fix for wrong number of expected args 2011-10-17 10:17:18 +02:00
Cédric Pasteur 902cbaf7a1 Fixed error with memalloc and const value with when 2011-10-04 14:34:44 +02:00
Cédric Pasteur 81947eca40 Made linearity field not optional
This helped solve a few bugs with linear types,
for instance when using automata.
The intermediate code is not well-typed (wrt to
linear types only), after the encoding of automata.

Cédric Pasteur f45e30d207 Yet another special case for iterators 2011-06-07 10:49:36 +02:00
Cédric Pasteur de3a61557b Improvements on Schedule_Interf
Only take into account optimized types.
Reuse code from Interference to compute uses.

Cédric Pasteur b7ba8e7913 Remove useless case
As targeting is only done for linear variables, 
this case is already dealt with by 
coalesce_linear_vars

Cédric Pasteur 448c163181 Dsatur coloring algorithm
It is not completely generic, as we need to know 
the difference between affinity and interference
edges.
